Rename playbook/ to 07-playbook/ for consistent numbering (#173)

* docs: rename playbook/ to 07-playbook/ for consistent chapter numbering

Closes #156

* docs: extract 07-playbook.md and rename recipe directory to recipes/

Separates the chapter entry point (07-playbook.md) from the recipe
pages (recipes/). All chapters now follow the NN-name.md pattern and
the recipe directory has a self-explanatory name.

* fix: use playbook/ in markdown links to match URL routing

The remark link rewriter maps directory names to URLs. Since recipe
pages have section: "playbook/..." in frontmatter, their URLs are
/playbook/X/ not /recipes/X/. Markdown links must use playbook/ to
produce correct URLs after rewriting.
